We received broken from warehouse the first time and had to send back. We received again and it did NOT punch holes through all of the paper. We tried adjusting metal cutters and that did not help. We applied extreme pressure to the handle (which you aren't supposed to do)..that didn't work. Holes would only punch through half of the stack or punch through one or two holes completely and the third hole would only partially punch through. Very Frustrating, especially for the money you pay for it! We ordered another brand of heavy duty brand hole punch after this one with same exact results! You are better off buying a light or medium duty hole punch, which works so much better than this monstrosity! Don't waste your money.

You must use your whole body weight several times to get this to punch though all of your pages. Even if you're only trying to punch 20. Even then it still does not punch through all the pages. It gets paper bits everywhere. Very poor quality. The problem is that I can't find a heavy duty three hole punch that gets good reviews! Why can't someone make a product that works?
